Herbs play an important role in human’s day-to-day life. They are used in mainly three sectors food, pharmaceutical and nutraceutical in industries. Today we fear to have fruit or vegetable brough from market due to the involvement of the chemical pesticides in the farming. Thus there arises a need of organic pesticides which will help both the farmer as well as customer on the same hand. There several herbs with active components which may prevent the pest impact on the crops which should be extracted from respective plants and has to be mixed in a fixed proportion. The different raw materials kokum, cardamom, neem (Azadirchta indica), fennel, etc. Thus our main objective is to extract out a pure organic pesticide from herbal extracts. Raw materials are selected based on the anti-microbial, anti-inflammatory, anti-tumour properties. Oleic acid was found to be 25-54% neem oils fatty acid content and has property to produce soap. By using UV- spectrometer, we found the concentration of oleic acid in the Neem leaves. From the reviews and experimentation, the concentration of oleic acid increases with increase in temperature as well as RPM.
